I watched this on a whim, only to learn that I had been doing several things incorrectly, and/or forgotten some useful things, e.g., if you move two spaces, you don't drop off (or pick up) a worker in each space, but rather only that of your destination. I don't know why I had trouble with this, it is actually spelled out fairly clearly. Or that you may move your stack to an occupied space, not pay, and not take the action. I'm wondering if I've been paying wrong for the Mosque tiles, too. Arg.

Istanbul is an AWESOME game! One of my all time favourites! Edit: BTW... I would highly, highly recommend the Istanbul: Mocha & Baksheesh expansion which makes the game amazing! The additional option of coffee really opens the game up. It really was what made Istanbul awesome for me!
